Definitions

  • the invention relates to a reinforcing ply for a pneumatic vehicle tire, preferably for a belt bandage ply of a pneumatic vehicle tire, wherein the reinforcing ply comprises reinforcements with at least one multifilament yarn and wherein said at least one multifilament yarn consists of polyamide which is largely based on renewable raw materials.
  • Such a reinforcing layer is known from DE 10 2010 017 786 AI. to
  • Polyamide 10.10 represents a polycondensation product of 1,10-cecethylenediamine and 1,10-decanedioic acid, both monomers being obtained from castor oil. Thus, polyamide 10.10 is based 100% on natural, renewable resources and not on petroleum.
  • Reinforcement layers for pneumatic vehicle tires and their strength members are known to those skilled in construction and material in various designs.
  • yarns or cords are used in the bead area, as carcass material, for belt layers and as a belt bandage.
  • the yarns or cords are embedded in a rubber compound during the manufacture of the tires to be rubberized
  • Reinforcements can be used in the tire.
  • the belt bandage is used in pneumatic vehicle tires, especially when
  • Bead region extends and there is usually anchored by wrapping tensile bead cores, having a radially outer, tread grooves having rubber tread and a belt between the rubber tread and the carcass, arranged between the belt and tread.
  • the belt bandage can be formed in one or more layers, covers at least the belt edges and contains parallel and substantially in
  • Circumferentially extending reinforcements in the form of cords which in a
  • Rubber compound are embedded.
  • the belt bandage is embedded in an unvulcanized rubber compound in the form of layers during tire production
  • Reinforcements applied which are wound or spooled on the belt.
  • the reinforcements are embedded in rubber for such layers by a calender in the longitudinal direction a calender of substantially parallel filiform reinforcing materials, which are usually pretreated with a thermal impregnation and / or for better adhesion to the embedding rubber in the known manner or pass through an extruder to coat with the rubber compound.
  • the tire usually extends in the shoulder area by the survey by up to 2% and in the center region by up to 4% compared to the unvulcanized blank when the blank is wound on a flat drum.

  • Polyamide 10.10 in the belt bandage position of a pneumatic vehicle tire could be improved.
  • Two properties of the reinforcement are hereby particularly desirable: on the one hand, the polyamide material should be sufficiently stretchable that an advantageously high shrinkage is obtainable, on the other hand, the module should be in an advantageously high range.
  • Polyamide 10.10 which has long and soft chains in the acid and diamine content, is comparatively well stretchable and therefore has a desired high shrinkage, but a comparatively disadvantageously low modulus.
  • Polyamide 6.6 has in the acid and diamine average chain lengths, is also still stretchable well and therefore has a still suitable shrinkage and a suitable module, but is not umwind- and resource-friendly to produce.
  • Polyamide 4.4 is relatively poor drawable due to its small chain lengths in the acid and diamine, therefore, has a rather disadvantageous low shrinkage, but an advantageous high modulus.
  • the invention is based on the object, a reinforcing layer with reinforcements for a pneumatic vehicle tire, preferably for a belt bandage position of a
  • the multifilament yarn consists of polyamide 4.10.
  • a multi-filament yarn consisting of polyamide 4.10 is created, which is partially biobased.
  • One monomer of the two monomers of polyamide 4.10 is largely based on renewable raw materials and not on crude oil, making it environmentally friendly and resource-friendly.
  • Polyamides are polycondensation products of dicarboxylic acids and diamines.
  • An economically important dicarboxylic acid is sebacic acid, which is produced, for example, from castor oil obtained from the seeds of the Rizinzussstaude.
  • the "10s" component of polyamide 4.10 is based on sabacic acid.
  • the eco-friendly character is further emphasized by the fact that the caster grows under conditions in which it does not compete with other crops.
  • polyamide 4.10 fibers have a constant quality compared to natural fibers and can be produced as continuous fibers. Thus, a consistent product quality can be ensured and the processing reliability is given.
  • Polyamide 4.10 is characterized by a polymer structure which is well stretchable and has a suitably high shrinkage with a suitable module. Compared to the other polyamides polyamide 4.10 thus represents a good compromise between shrink and modulus, which is particularly suitable for use as a strength carrier in a belt bandage position.
  • polyamide 4.10 is characterized by a low water absorption capacity, whereby the good properties, such as the breaking strength, even when exposed to moisture.
  • polyamide 4.10 has a great similarity to polyamide 6.6, which is frequently used in reinforcing layers. In this way, an easy replacement of polyamide 6.6 (PA 6.6) by polyamide 4.10 (PA 4.10) while maintaining, for example, the adhesive system used is possible.
  • the values are measured on an untwisted yarn.
  • the shrinkage is determined according to ASTM D885 and ASTM D4974.
  • the force-strain data are determined according to ASTM D855M.
  • the strength member is a cord twisted from at least two twisted multifilament yarns.
  • Multifilamentgarnes or the Cordes is achieved an improved fatigue strength of the strength member compared to untwisted reinforcements. It is expedient if the multifilament yarn has a fineness of 100 to 5000 dtex and a twist of 100 to 600 t / m. Such multifilament yarns are easy to produce and are suitable for use as a strength carrier in
  • the cord consists of 2 or 3 endverglassten Multifilamentgamen.
  • all multifilament yarns of the cord are made of polyamide 4.10.
  • a multifilament yarn of the cord does not consist of polyamide 4.10.
  • at least one multifilament yarn of the cord does not consist of polyamide 4.10. It is then a so-called hybrid cord. This is then based at least partially on renewable raw materials, is designed to save resources and offers the further advantage of the possibility of defined setting of the cord by a targeted selection of materials not existing polyamide 4.10 Games.
  • the invention also relates to a pneumatic vehicle tire having a reinforcing ply according to a reinforcing ply configured above.
  • Reinforcement layer is a belt bandage layer or a bead reinforcement such as a chipper or a pinball machine.
  • Pneumatic vehicle tires are mass-produced products where the partial replacement of petroleum-based materials with non-petroleum materials leads to a particularly significant resource conservation effect. It has also been shown that
  • a car tire may have a belt bandage layer of cords of the following construction:
  • Variant A construction / material: 1400x1 / polyamide 4.10
  • Variant B construction / material: 940x2 / polyamide 4.10
  • the yarn twist is equal to the cord rotation, only in the opposite direction.
